Technical field

The present invention relates to the metallic paint technical field.The invention particularly relates to the goods and the manufacture method thereof of producing for the antibiotic property and/or the antifungal activity of the base material that increases metal coat.

Background technology

In recent years, the harmfulness of the germ contamination of potential everyday exposure generation receives very big concern.For catering to the day by day concern of consumer to this field, producer has begun to introduce antiseptic in various household products and goods.For example, the polypropylene cutting board of some plate, liquid soap etc. all contain antimicrobial compound.

In addition, the risk of bacterial infection is also very general in the medical space.For example, the various medical articles that are used to contact patient's body fluid have been designed especially.The time of this contact may be lacked (being common in wound dressing) or long (being common in the heart valve of implanting in the acceptor body).The time of contact of some goods such as conduit may be very short also may be very long.Relative other short goods with patient time of contact include but not limited to burn dressing and contact lenses.Usually include but not limited to implanting prosthetic than other long goods time of contact with the patient.

Goods have caused infection risk with contacting of body fluid.This risk may very serious even threat to life.In addition, infection may cause huge cost, longer or extra hospital stays.For example, relevant with dressing infection may increase the order of severity that the fire victim is hurt.In addition, relevant with implanting prosthetic infection may need to replace this equipment.

Therefore, prior art has been attempted some and has been helped to reduce bacterial infection risks and/or even the method stopping to infect.A kind of method of also expecting is to use antiseptic and/or bactericide.

For a lot of goods, the most frequently used antiseptic is a triclosan.Although, proved that can't arrive other base materials comprises fabric and fiber surface with quite simple in this compound introducing liquid or the polymeric media.All thirst for for a long time for providing effective, durable and the long acting antibiotic performance on fabric face especially dress material and the film surface.With triclosan is extremely difficult realize this hope, (triclosan is washed any this type of surface easily off) especially all the more so when necessarily requiring washability.In addition, although confirmed the effect of triclosan as antimicrobial compound, in these compounds chlorine have a Diazolidinyl Urea, and this need fight off with fiber, film and fabric for using it for dress material.

In addition, also have some comprise with the acrylic acid of triclosan coextrusion and/or the commercially available fabric product of acetic ester fiber (as Celanese with Microsafe ^TMThis type of acetate fabric sold and Acordis are with Amicor ^TMThis type of acrylic acid fabric of selling).But this application only limits to those fiber types, and it does not work for all natural fibers, particularly for and/or inoperative at fabrics such as polyester, polyamide, cotton, elastic fibers.In addition, this coextrusion processes cost is very high.

Developed recently the silver-containing inorganic bactericide and on a variety of different substrate materials and the surface and within as antiseptic.Particularly, this bactericide has been fit to be incorporated into some fabric that selectivity is provided in the spinning of melt-spun synthetic fibers and shows antibacterial characteristics inherently, as Japanese unexamined patent H11-124729 number.In addition, attempted on fabric and yam surface adopting this specific bactericide, but see from the durability viewpoint hardly can be successful.Adopt the Local treatment of this compound also never successfully on fabric or yarn substrate, to be used as durable surface layer or coating.

Although this money base reagent provides excellent, durable antibiotic property, up to the present, this also is that unique method that gets long-acting, washable, the money base antibiotic fabric is provided in the prior art.But, because in order to provide enough antibacterial activities (antibacterial activity is relevant to its surperficial performance from the internal migration of fiber own with this compound) to need a large amount of money base compounds, this melt spun fibre manufacturing cost is high.

In addition since in the prior art with the method for metal such as silver-colored coated fiber, contain much that ag material is difficult to make and/or manufacturing cost is high.

From using aldehyde to depositing silver from the solution that contains silver salt the earliest, the electroless deposition methods of metal on various base materials is known.Recently, after the nickel-phosphorus alloy of finding some alloys such as electroless deposition has special performance and because this method is used to plate plastics day by day, produces optics, electronics and optoelectronic device, the employing of electroless process has received concern.

Electroless plating solution contains slaine, reducing agent, pH conditioning agent, complexant and more than one additives usually and comprises the performance of bathing stability, film properties and metal deposition rates with control.Desirable electroless plating solution only deposits metal on the goods of dipping, and never can be deposited on pool side or be deposited as fine powder as film.All parts of goods of dipping all must thoroughly clean before plating.Dust that exists on the goods or oxide can disturb uniform deposition also can cause the caking property of metal deposit to reduce.

Metal is to the catalytic site of the existence of using the seed material that need contact with the product surface of thorough cleaning to provide electroless plated metal to deposit of electrical insulator.The solution that contains inferior tin of acid chlorization and acid chlorization palladium is adopted in the activation on surface that is used to not have the non-conductive and dielectric material of electric metal plating usually.Primary catalyst be have as with the independent solution of the inferior tin of acid chlorization of the reducing agent of after-applied palladium bichloride to produce the catalytic site of Metal Palladium at the product surface place of cleaning.The substance of palladium exists and chemism is the precondition that starts electroless plating.Can replace two-step catalysis agent system with the catalyst solution of palladium that contains pre-reaction and stannous chloride.

U.S.Pat.No.3,632,435 have confirmed that tin and palladium salt can be used for surface active, and comprise that other precious metal salt of use replaces palladium.The document has also been emphasized as previously mentioned with the passivation of the selected part of the catalytic surface of Ya Xi and palladium ion activation or has been covered.In this case, passivation relates to the application of destabilizing agent.One class destabilizing agent comprises multivalence hydrolyzable metal ion, and as lead, iron and aluminium ion, these ions have the ability that stannous ion is oxidized to the tetravalent tin ion.The tetravalent tin ion does not generate the catalytic site of the element palladium be used to deposit no electric metal layer with the palladium solution reaction.In some other document, mention activation, only adopt stannous chloride for silver metallized technology.

According to U.S.Pat.No.3,632,435, the chelating agent that is used for noble metal comprises and contains sour functionality so that the organic compound of another kind of destabilizing agent to be provided, as binary acid.Acid chelating agent mainly acts on the noble metal of catalytic surface such as the palladium covering its catalytic performance, thereby prevents that electroless metal deposition from taking place in processed zone.Acid treatment can as under other situation to promote the electroless plating of top layer plating on metallic conductor, prevent that simultaneously metal is deposited on the dielectric material around the metallic conductor.U.S.Pat.No.5,167,992 adopt the passivator acid solution from removing precious metal ion with the dielectric surface after the precious metal salt solution processing.Suitable passivator acid comprises organic acid and inorganic acid.

Yet these methods can not obtain to discharge in the early stage the metal coat fiber or the material of high percentage metal ion.In addition, be that silver and product are used for its those embodiments antibiotic and/or anti-fungal property for metal wherein, these methods can not obtain higher silver ion release rate.

Therefore, need the method for coated fiber or other base material, this method makes it possible to design metal coating to discharge the metal ion of high percentage in the early stage.In addition, also need the fiber or the base material of silver coating, it can use being used for its product antibiotic and/or anti-fungal property, thereby because the higher release rate of initial stage silver ion increases the effect of the base material that silver applies.
